A servomotor is a rotary actuator that allows for precise control of angular position, velocity and acceleration. Most modern servomotor are designed and supplied around a dedicated control module. So that servomotor doesn’t require a driver. A microcontroller PWM pin can be used directly to control the servomotor. From picture it is seen that the […]

Let us control a motor using Fast PWM 8bit of Timer1. In order to control a 12V dc motor we need a driver IC that L293D. In this program we use Timer1 OCR1A and OCR1B active at 8bit Fast PWM and two pin to control two dc motor. Here to control motor1 the driver has
PWM stands for pulse wide modulation. In AVR family there are three types of waveform generating modes The relationship between output voltage and duty cycle is A PWM signal is nothing but a square wave in which the tine period (Ton+Toff) remain the same but the duty cycle changes. Basically all PWM mode operate with
